I have been looking high and low for the air dam and grille for a saturn sl. found only one place that carries the grill but no luck on the air dam and lower bumper cover. right now I can look through the grille hole and see the ground and the radiator is exposed to the air to where it would be easy to take it out on a curb. Could find no parts that go in that area. thinking of make some myself out of aluminum, sort of a belly pan.

 

The spring loaded air dam is likely a trip to the junkyard.
Same with the grille.

I'm not sure what you mean by lower bumper cover.
It sounds like the protective plastic shield under the front of the engine bay was trashed in the previous wreck and never replaced (along w the grille and air dam). It comes in multiple pieces with those center push snap type connectors.
Again, junkyard diving.

Might want to put some chicken wire or robust netting over the grille opening for now before you catch a rock on the highway at 70mph

 

OK Thanks, I will check the local junk yards, the air conditioning radiator already have a few dents mashed in it. Still works though.
